BACKGROUND OF THE INVENTION

1. Field of the Art

The disclosure relates to the field of electronic devices, and more particularly to the field of input and output methods for interaction within software applications.

2. Discussion of the State of the Art

In the field of electronic devices, separate handheld controllers are commonly used to enable a user to provide interaction or receive feedback from a host device, such as a personal computer or a video gaming console. These controllers may be connected via a wired or a wireless connection, and generally are paired with only a single host device at any given time. When a user wishes to utilize multiple controllers, they must be connected individually to the host device (for example, connecting both a keyboard and a mouse to a personal computer, using two separate ports on the computer). This requires a number of separate communication connections between a host device and controllers, and if a host device or controller have mismatched communication hardware, they are incompatible and cannot be used. Additionally, controllers generally are designed for a particular purpose (such as for a particular type of video game or computer application), and require a user to interact with them in a specific fashion, such as to hold the controller in a particular manner to have manual access to all of its functions. This can be awkward or even unhealthy for the user, and restrictive of the manner with which they interact with the device.

Additionally, users typically interact with a fitness device, whether viewing or not viewing a static screen. For example, while running on a treadmill a user may choose to view a static screen displaying a television show. The elements in a television show are static, in that the elements do not change behavior based on the user's interactions with the television show, but instead perform predetermined actions. An example of a dynamic screen is that of a video game. The user interacts with a remote and influences the activity of the elements in the video game. At most, the user may interact with the screen performing an activity independent of actions related to interacting with the fitness device.

Furthermore, with the rapidly-expanding virtual reality industry, new interaction methods are being explored including a variety of controllers for gaming, wands, and motion-based input devices including gloves and camera-based hand tracking. However, these devices all focus on interacting with a user's hands, and ignore other parts of the body that could be used to improve interaction and immersion, while also expanding the possibilities for data collection.

What is needed, is a means to enable users to connect a variety of control and tracking devices to a host device regardless of their communication means, that also addresses the need for controllers that a user may interact with regardless of their position or movement, for interaction with mixed-reality electronic applications.

Conceptual Architecture

FIG. 7 is a block diagram of an exemplary system architecture 700, illustrating the use of nested-communication control devices 701, 702 a-n with a variety of electronic systems 710, according to a preferred embodiment of the invention. According to the embodiment, a control device 701 may be connected to a plurality of electronic systems 710 such as including (but not limited to) a personal computer 711, video gaming console 712, media center (for example, a home theater system) 713, or mobile device 714 (for example, a smartphone or tablet computing device). Connection may occur via a variety of means, but according to the embodiment and as envisioned by the inventors, an ideal method of connection is via wireless connectivity means over the air. Exemplary communication protocols or technologies for such connectivity may include (but are not limited to) cellular radio communication, BLUETOOTH™, ANT™, WiFi, near-field communication (NFC), or other connectivity means.

According to the embodiment, a plurality of additional control devices 702 a-n may be paired with a primary control device 701 via a variety of connectivity means. When connected in this manner, input from a user interacting via an additional control device 702 a-n may be transmitted to primary control device 701, which may then convey the interaction to a plurality of connected electronic systems 710. Feedback, if provided by an electronic system 710, may then be received by primary control device 701 and conveyed to additional control devices 102 a-n as needed (for example, if a user interacts via a particular additional control device 102 a, and an electronic system 110 provides feedback intended specifically for that user or that device). It should be appreciated that not all control devices need to utilize similar connectivity means. For example, if a primary control device 101 is operating both a BLUETOOTH™ and a WiFi radio for wireless communication, an additional control device 102 a may connect via BLUETOOTH™ while a second additional control device 102 b may connect using WiFi. In this manner, a primary control device 101 may be considered a means to unify various connectivity means to facilitate communication between a plurality of electronic systems 110 and a plurality of additional control devices 102 a-n of varying design and operation.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

FIG. 1 is a diagram of an exemplary hardware arrangement 100 for natural torso tracking and feedback for electronic interaction according to a preferred embodiment of the invention, illustrating the use of multiple tethers 110 a-n and a movable torso harness 120. According to the embodiment, a plurality of tethers 110 a-n may be affixed or integrally-formed as part of a handle or railing 130, such as handlebars found on exercise equipment such as a treadmill, elliptical trainer, stair-climbing machine, or the like. In alternate arrangements, specifically-designed equipment with integral tethers 110 a-n may be used, but it may be appreciated that a modular design with tethers 110 a-n that may be affixed and removed freely may be desirable for facilitating use with a variety of fitness equipment or structural elements of a building, according to a user's particular use case or circumstance. Tethers 110 a-n may then be affixed or integrally-formed to a torso harness 120, as illustrated in the form of a belt, that may be worn by a user such that movement of their body affects tethers 110 a-n and applies stress to them in a variety of manners. It should be appreciated that while a belt design for a torso harness 120 is shown for clarity, a variety of physical arrangements may be used such as including (but not limited to) a vest, a series of harness-like straps similar to climbing or rappelling equipment, a backpack, straps designed to be worn on a user's body underneath or in place of clothing (for example, for use in medical settings for collecting precise data) or a plurality of specially-formed clips or attachment points that may be readily affixed to a user's clothing. Additionally, a torso harness 120 may be constructed with movable parts, for example having an inner belt 121 that permits a user some degree of motion within the harness 120 without restricting their movement. Movement of inner belt 121 (or other movable portions) may be measured in a variety of ways, such as using accelerometers, gyroscopes, or optical sensors, and this data may be used as interaction with software applications in addition to data collected from tethers 110 a-n as described below.

As a user moves, their body naturally shifts position and orientation. These shifts may be detected and measured via tethers 110 a-n, for example by detecting patterns of tension or strain on tethers 110 a-n to indicate body orientation, or by measuring small changes in strain on tethers 110 a-n to determine more precise movements such as body posture while a user is speaking, or specific characteristics of a user's stride or gait. Additionally, through varying the quantity and arrangement of tethers 110 a-n, more precise or specialized forms of movement may be detected and measured (such as, for example, using a specific arrangement of multiple tethers connected to a particular area of a user's body to detect extremely small movements for medical diagnosis or fitness coaching). This data may be used as interaction with software applications, such as for virtual reality applications as input for a user to control a character in a game. In such an arrangement, when a user moves, this movement may be translated to an in-game character or avatar to convey a more natural sense of interaction and presence. For example, in a multiplayer role playing game, this may be used to facilitate nonverbal communication and recognition between players, as their distinct mannerisms and gestures may be conveyed in the game through detection of natural torso position and movement. In fitness or health applications, this data may be used to track and monitor a user's posture or ergonomic qualities, or to assist in coaching them for specific fitness activities such as holding a pose for yoga, stretching, or proper running form during use with a treadmill. In medical applications, this data may be used to assist in diagnosing injuries or deficiencies that may require attention, such as by detecting anomalies in movement or physiological adaptations to an unrecognized injury (such as when a user subconsciously shifts their weight off an injured foot or knee, without consciously realizing an issue is present).

Through various arrangements of tethers 110 a-n and tether sensors (as described below, referring to FIGS. 2-3), it may be possible to enable a variety of immersive ways for a user to interact with software applications, as well as to receive haptic feedback from applications. For example, by detecting rotation, tension, stress, or angle of tethers a user may interact with applications such as virtual reality games or simulations, by using natural body movements and positioning such as leaning, jumping, crouching, kneeling, turning, or shifting their weight in various directions to trigger actions within a software application configured to accept torso tracking input. By applying haptic feedback of varying form and intensity (as is described in greater detail below, referring to FIG. 2), applications may provide physical indication to a user of software events, such as applying tension to resist movement, pulling or tugging on a tether to move or “jerk” a user in a direction, or varying feedback to multiple tethers such as tugging and releasing in varying order or sequence to simulate more complex effects such as (for example, in a gaming use case) explosions, riding in a vehicle, or walking through foliage.

It should be appreciated that while reference is made to virtual reality applications, a wide variety of use cases may be possible according to the embodiment. For example, torso tracking may be used for fitness and health applications, to monitor a user's posture or gait while walking, without the use of additional virtual reality equipment or software.

FIG. 2 is a diagram illustrating a variety of alternate tether arrangements. According to various use cases and hardware arrangements, tethers 110 a-n may utilize a variety of purpose-driven designs as illustrated. For example, a “stretchable” tether 210 may be used to measure strain during a user's movement, as the tether 210 is stretched or compressed (for example, using piezoelectric materials and measuring electrical changes). Such an arrangement may be suitable for precise measurements, but may lack the mechanical strength or durability for gross movement detection or prolonged use. An alternate construction may utilize a non-deforming tether 220 such as a steel cable or similar non-stretching material. Instead of measuring strain on the tether 220, instead tether 220 may be permitted a degree of movement within an enclosure 222 (for example, an attachment point on a torso harness 120 or handlebar 130), and the position or movement 221 of the tether 220 may be measured such as via optical sensors. In a third exemplary arrangement, a tether 230 may be wound about an axle or pulley 231, and may be let out when force is applied during a user's movement. Rotation of the pulley 231 may be measured, or alternately a tension device such as a coil spring may be utilized (not shown) and the tension or strain on that device may be measured as tether 230 is extended or retracted. In this manner, it may be appreciated that a variety of mechanical means may be used to facilitate tethers and attachments for use in detecting and measuring natural torso position and movement, and it should be appreciated that a variety of additional or alternate hardware arrangements may be utilized according to the embodiments disclosed herein.

Additionally, through the use of various hardware construction it becomes possible to utilize both “passive” tethers that merely measure movement or strain, as well as “active” tethers that may apply resistance or movement to provide haptic feedback to a user. For example, in an arrangement utilizing a coiled spring or pulley 231, the spring or pulley 231 may be wound to retract a tether and direct or impede a user's movement as desired. In this manner, various new forms of feedback-based interaction become possible, and in virtual reality use cases user engagement and immersion are increased through more natural physical feedback during their interaction.

By applying various forms and intensities of feedback using various tether arrangements, a variety of feedback types may be used to provide haptic output to a user in response to software events. For example, tension on a tether may be used to simulate restrained movement such as wading through water or dense foliage, walking up an inclined surface, magnetic or gravitational forces, or other forms of physical resistance or impedance that may be simulated through directional or non-directional tension. Tugging, retracting, or pulling on a tether may be used to simulate sudden forces such as recoil from gunfire, explosions, being grabbed or struck by a software entity such as an object or character, deploying a parachute, bungee jumping, sliding or falling, or other momentary forces or events that may be conveyed with a tugging or pulling sensation. By utilizing various patterns of haptic feedback, more complex events may be communicated to a user, such as riding on horseback or in a vehicle, standing on the deck of a ship at sea, turbulence in an aircraft, weather, or other virtual events that may be represented using haptic feedback. In this manner, virtual environments and events may be made more immersive and tangible for a user, both by enabling a user to interact using natural body movements and positioning, as well as by providing haptic feedback in a manner that feels natural and expected to the user. For example, if a user is controlling a character in a gaming application through a first-person viewpoint, it would seem natural that when their character is struck there would be a physical sensation corresponding to the event; however, this is not possible with traditional interaction devices, detracting from any sense of immersion or realism for the user. By providing this physical sensation alongside the virtual event, the experience becomes more engaging and users are encouraged to interact more naturally as their actions results in natural and believable feedback, meeting their subconscious expectations and avoiding excessive “immersion-breaking” moments, which in turn reduces the likelihood of users adopting unusual behaviors or unhealthy posture as a result of adapting to limited interaction schema.

Haptic feedback may be provided to notify a user of non-gaming events, such as for desktop notifications for email or application updates, or to provide feedback on their posture for use in fitness or health coaching. For example, a user may be encouraged to maintain a particular stance, pose, or posture while working or for a set length of time (for example, for a yoga exercise application), and if their posture deviates from an acceptable range, feedback is provided to remind them to adjust their posture. This may be used in sports, fitness, health, or ergonomic applications that need not utilize other aspects of virtual reality and may operate as traditional software applications on nonspecialized computing hardware. For example, a user at their desk may use an ergonomic training application that monitors their body posture throughout the work day and provides haptic reminders to correct poor posture as it is detected, helping the user to maintain a healthy working posture to reduce fatigue or injuries due to poor posture (for example, repetitive-stress injuries that may be linked to poor posture while working at a computer).

FIG. 3 is a diagram of an additional exemplary hardware arrangement 300 for natural torso tracking and feedback for electronic interaction according to a preferred embodiment of the invention, illustrating the use of angle sensors 312,321 a-n to detect angled movement of a tether 320. According to one exemplary arrangement, a tether 310 may be affixed to or passed through a rotating joint such as a ball bearing 311 or similar, to permit free angular movement. During movement, the angular movement or deflection 312 of a protruding bar, rod, or tether segment 313 may be measured (for example, using optical, magnetic, or other sensors) to determine the corresponding angle of tether 310. In this manner, precise angle measurements may be collected without impeding range of motion or introducing unnecessary mechanical complexity.

In an alternate hardware arrangement, the use of angle sensors 321 a-n enables tracking of a vertical angle of a tether 320, to detect and optionally measure vertical movement or orientation of a user's torso. When tether 320 contacts a sensor 321 a-n, this may be registered and used to detect a general vertical movement (that is, whether the tether is angled up or down). For more precise measurements, the specific hardware construction of a sensor 321 a-n may be varied, for example using a pressure-sensing switch to detect how much force is applied and use this measurement to determine the corresponding angle (as may be possible given a tether 320 of known construction). It should be appreciated that various combinations of hardware may be used to provide a desired method or degree of angle detection or measurement, for example using a conductive tether 320 and a capacitive sensor 321 a-n to detect contact, or using a mechanical or rubber-dome switch (as are commonly used in keyboard construction) to detect physical contact without a conductive tether 320.

The use of angle detection or measurement may expand interaction possibilities to encompass more detailed and natural movements of a user's body. For example, if a user crouches, then all tethers 110 a-n may detect a downward angle simultaneously. Additionally, data precision or availability may be enhanced by combining input from multiple available sensors when possible (for example, utilizing adaptive software to collect data from any sensors that it detects, without requiring specific sensor types for operation), for example by combining data from tethers 110 a-n and hardware sensors such as an accelerometer or gyroscope, enabling multiple methods of achieving similar or varied types or precision levels of position or movement detection. Similarly, when a user jumps then all tethers may detect an upward angle simultaneously. However, if a user leans in one direction, it may be appreciated that not all tethers 110 a-n will detect the same angle. For example, tethers 110 a-n in the direction the user is leaning may detect a downward angle, while those on the opposite side would detect an upward angle (due to the orientation of the user's torso and thus a worn torso harness 120). In this manner, more precise torso interaction may be facilitated through improved detection and recognition of orientation and movement. Additionally, it may be appreciated that sensors 321 a-n may be utilized for other angle measurements, such as to detect horizontal angle. For example, if a user is wearing a non-rotating torso harness 120, when they twist their body a similar stress may be applied to all attached tethers 110 a-n. Without angle detection the precise nature of this movement will be vague, but with horizontal angle detection it becomes possible to recognize that all tethers 110 a-n are being strained in a similar direction (for example, in a clockwise pattern when viewed from above, as a user might view tethers 110 a-n during use), and therefore interpret the interaction as a twisting motion (rather than, for example, a user squatting or kneeling, which might apply a similar stress to the tethers 110 a-n but would have different angle measurements).

FIG. 4A is a diagram illustrating an exemplary physical arrangement of paired, nested-communication wireless control devices 400 a-b, according to a preferred embodiment of the invention. According to the embodiment, a plurality of wireless control devices 400 a-b may be “paired” to a plurality of electronic host devices 410 (for example, including but not limited to a gaming console device, personal computer, mobile device such as a smartphone or tablet computing device, media device, or other electronic devices that may receive user interaction via a physically-separate controller or controllers) via a wireless communication protocol such as including (but not limited to) BLUETOOTH™, WiFi, NFC, ZIGBEE™, cellular radio frequencies (for example, either via an existing GSM or other cellular network, or by using cellular frequencies to create an ad-hoc or “mesh” network between devices as needed), or other suitable wireless communication protocols or technologies. According to the embodiment, two physically-separate controllers 400 a-b may be paired to a host 410, for a user to hold one controller in each hand for ease of manipulation and ergonomic comfort. For example, a user may hold the controllers at a comfortable angle and distance while seated, enabling a greater level of comfort than would be possible with a single controller manipulated with both hands. For example, a user may grasp a controller in each hand during exercise or full-body interactive gameplay, such as while running on a treadmill or interacting with a virtual fitness trainer such as using a NINTENDO WII™ gaming console. It should also be appreciated that a control device 400 a-b may optionally be paired with more than one host device 410, for example using a single controller to interact with multiple computers or mobile devices, for example for giving a presentation or directed instruction, where an instructor may interact directly with students' devices.

FIG. 4B is a diagram illustrating an exemplary physical arrangement of paired, nested-communication wireless control devices 400 a-b, illustrating communication via an adapter 420 according to a preferred embodiment of the invention. According to the embodiment, a communication adapter 420 may be utilized to facilitate communication between a plurality of controllers 400 a-b and a plurality of host devices 410, for example to connect multiple physical controllers and present them to a host as a single “virtual controller” (as may be required according to a particular software application being interacted with, for example a video game that requires a unitary controller design) or to bridge communication between host and controllers that may otherwise be incapable of communicating (for example, if one device relies solely on a BLUETOOTH™ radio for connectivity while other use WiFi, or if two different communication protocols are in use). Additionally, a communication adapter may be operated by a control device, for example in an arrangement where multiple additional or “secondary’ controllers communicate with a designated “primary” controller, which in turn communicates with a host device, for example by receiving communication from each additional controller and presenting all communication to a host device in a “nested-communication” arrangement wherein the primary controller serves as a communication adapter between other controllers and a host (as described below, referring to FIGS. 5-6). For example, a primary controller may be operate a communication adapter 420 to bridge communication between fitness trackers or wearable devices (for example, such as FITBIT™, APPLE WATCH™, or MICROSOFT BAND™ devices) to a plurality of host devices 410, such as to integrate fitness or health information (as is commonly tracked by wearable devices) with video games or other software applications. Such an arrangement can also be used to bridge data between devices from different vendors or running different software or operating systems, for example to integrate health data from an APPLE WATCH™ device with a MICROSOFT XBOX™ gaming console, or fitness information from a FITBIT™ fitness tracker with a SONY PLAYSTATION™ gaming console, or other combinations of hardware, software, and vendors.

For example, according to a particular intended use such as for interaction with a home gaming console (for example, Microsoft XBOX™ or Sony PLAYSTATION™), a particular wireless protocol or hardware technology may be utilized, or a control device 400 a-b may be configured with hardware means to utilize a number of communication protocols according to a particular use, while a user may be given an option to select a desired protocol or frequency for use. For example, a control device 400 a-b configured for use with a desktop computer may be configured to utilize BLUETOOTH™ radio communication in the 2.4 GHz frequency range. A hardware switch or button 401 b may optionally be provided whereby a user may select a different frequency as needed, for example a radio frequency in the 5 GHz range for use over a WiFi network instead of BLUETOOTH™, for example to increase range or speed or to avoid interference from other devices (for example, many microwave ovens used within a home or office may cause interference in the 2.4 GHz frequency band). The use of various wireless communication means may enable a user to hold a plurality of control devices 400 a-b in any position or manner they choose, improving ergonomics and relieving discomfort or the risk of repetitive-stress injuries that may occur using traditional control devices that generally require a user to grasp them in a particular fashion (for example, a computer keyboard that generally requires a user's arms and hands to be in an awkward alignment).

By utilizing wireless connectivity according to the embodiment, increased movement or positioning of a plurality of control devices may be used as an additional interaction method for users, for example using gesture-based input methods or position-tracking via internal hardware sensors such as accelerometers or gyroscopes. In this manner, additional forms of input may be enabled at a user's preference, increasing the quality or quantity of interaction possible with a particular control device and optionally reducing the need for specific hardware buttons. For example, a gesture-enabled control device may be programmed with a particular motion gesture that simulates the pressing of a “volume up” button, eliminating the need for a hardware button to perform that function.

According to the embodiment, a plurality of hardware buttons may be provided on a control device 400 a-b, and may vary in physical design or arrangement. For example, membrane or mechanical switch-based buttons may be utilized to provide a tactile sensation upon activation by a user (as is common in hardware keyboards intended for specific uses such as gaming or professional design), or capacitive touch-based buttons may be utilized to provide interaction in a more compact physical arrangement when tactile sensation may not be required (as is common in mobile applications, such as on-screen controls on a smartphone or tablet computing device).

Hardware buttons or other controls may be placed in various arrangements according to a particular use or desired functionality, for example a digital or analog “trigger”-style button 404 may be placed on the underside of a control device (shown in a side profile view) 400 c, for example for use in gaming application where a trigger-actuated function may be desirable (such as in first-person, racing, or simulator games). Another exemplary arrangement may be a number of buttons 402 a-n arranged in a particular fashion for use in navigation, such as to form a directional pad (D-pad) for use in a variety of games or applications, such as for navigating a media player interface or playing a video with a top-down view, such as a strategy or simulated board game. Other buttons may include large easily-reached buttons 401 a for use in games or applications when a user may need to quickly select and actuate a button without looking. Such buttons may be provided with a variety of identifying features such as readable text labels, colors, or physical shapes for example including (but not limited to) a square 401 a, circle 401 b, triangle 403 a or star-shaped 403 b control buttons.

According to the embodiment, a particular exemplary arrangement may be a pair of controllers that in effect act as a single “split controller”, wherein a user grasps each device in one hand and various functions are divided between the two devices to facilitate two-handed interaction without the need for using both hands on a unitary device. Controls may be arranged in a combined fashion, with directional buttons arranged about the top portion of each device, with a functional button positioned in the center of the directional buttons to provide an easily-reached button for interaction (for example, to “accept” or “click” on a menu item on-screen). Additionally, these combined control arrangements may then be coupled with a plurality of internal hardware sensors, such as accelerometers, gyroscopes, Hall effect sensors, or other hardware means of facilitating physical interaction through the capture and interpretation of sensor data, for example to enable interaction through the use of predefined or customizable gestures or position-tracking.

A variety of alternate or additional control device arrangements may be utilized in various combinations through a nested-communication protocol. For example, according to their planned use (such as for a particular game or application, or for use with a particular device or console) a user may select their preferred “primary” control device, and then pair a “secondary” control device with it. In this manner it may be appreciated that the specific number, style, or arrangement of buttons or other interactive features or physical design such as ergonomic shape or layout may vary widely, and a user may select the particular arrangements and combinations that appeal to them based on their particular needs or use. A variety of control device arrangements are described below, referring to FIG. 5, and it should be appreciate that any particular control device may be utilized as either a primary or secondary controller interchangeably, according to a user's preference. Additionally, through the use of various wireless communication technologies as described previously, additional hardware devices may be paired with a control device for nested communication. For example, fitness trackers (for example including, but not limited to, FITBIT™, MICROSOFT BAND™, or APPLE WATCH™ devices) may be paired via a wireless personal-area-network protocol such as BLUETOOTH™ or ANT™, for example to provide a user's biometric or health information along with interaction via a control device 400 a-b.

FIG. 5 is a diagram illustrating a variety of exemplary physical configurations of nested-communication wireless controllers 500 a-c, configured for various uses. According to one exemplary arrangement, a controller 500 a may be configured for optimum use as a media playback remote control, for example for use with a connected speaker or playback device, or with a home theater or media PC setup. According to such an arrangement, a number of buttons 501 a-n may be arranged for use in navigating an on-screen interface of a media device, for example to select audio or video content from a library for playback. A number of additional buttons 502 a-n may be arranged in a secondary location, to provide additional functions such as play/pause, stop, or menu functions such as to view additional information on selected media. According to a particular use, such a control device 500 a may be used as a primary controller, optionally with or without a secondary controller paired for nested communication, such as a user's fitness tracking device for use in monitoring heartbeat or other biometric changes during media viewing, or a gaming controller for use in playing interactive content presented through a media server or playback device (for example, playing a game on a ROKU™ or similar home theater device connected to a television).

According to another exemplary arrangement, a controller 500 b may be configured for a particular gaming use, for example formed with an appropriate physical shape and having control elements (buttons, switch, and other interactive hardware elements) arranged to best suit a simulation-type game. According to such a configuration, a control device 500 b may have a digital or analog “joystick”-type control element 510 for use in controlling a player's character or vehicle in a 360-degree three-dimensional virtual environment, for example for use in third-person action or adventure-type games. A plurality of additional buttons 511 a-n may be provided and arranged for easy one-handed use, such as to access a player's inventory, perform specific in-game actions (for example to jump, run, roll, or other movement controls), or to perform context-sensitive actions according to the nature of a particular game or application. For example, a simulator-oriented control device 500 b may be paired with a media remote control device 500 a as a secondary controller, enabling a user to navigate a media interface with the media remote 500 a as their primary control device, select a game from a media content menu, and then use the secondary control device 500 b to play the game. When finished playing, the user may then continue using their primary controller 500 a to further navigate the media interface, without the need to locate a remote control or switch controllers for different uses, as both controllers may be paired and in communication, even while one may be temporarily unused.

According to a further exemplary arrangement, a control device may be configured for use specifically as a secondary controller, for example as a throttle controller 500 c configured to be paired with a simulator controller 500 b for use in a two-handed “hands on throttle and stick” (HOTAS) setup commonly used in flight-simulation games. According to such a configuration, a control device 500 c may comprise a joystick or hat-switch control element 520 for navigation or for controlling a number of game or application functions with a user's thumb, generally positioned such that while holding control device 500 c a user's thumb is naturally aligned with the control element 520 for ease of use. Control device 500 c may further comprise an integrally-formed or removably affixed ergonomic portion 521, for example a removable or positionable rigid or soft panel, generally configured to conform to a user's hand or palm and align the user's hand for proper manipulation of various control elements. For example, in one exemplary arrangement, a control device 500 c may be configured with a body made of a rigid plastic material and having a removable plastic panel 521 shaped to fit a user's palm for a proper grip and alignment during use. Such a configuration may also be designed to accept a variety of alternate rigid panels 521, enabling a user to swap grip panels to configure the physical shape of control device 500 c to most comfortably fit their particular anatomy (for example, such a configuration has been used in the firearms industry to enable users to configure the grip of a handgun for proper posture and aiming). Control device 500 c may further comprise a plurality of additional control elements 522 a-n such as buttons or switches, for example arranged such that when properly aligned (as by using an ergonomic grip panel, as described previously) a user's fingers may naturally be aligned in a position for ideal activation of control elements 522 a-n. In this manner, it may be appreciated that a control device 500 a-c may be configured with ergonomic portions 521 in a variety of arrangements, and with various arrangements of control elements for optimal use when a user's hand is properly aligned and grasping control device 500 a-c, such that any particular control device 500 a-c may be tailored to fit a wide range of users' anatomies for optimal use, as well as to promote ergonomic comfort and physical health. For example, by encouraging users to find an optimum ergonomic fit, the risk of repetitive-stress injuries and other health concerns may be reduced.

FIG. 6 is a flow diagram illustrating an exemplary method 600 for nested communication between control devices and electronic systems, according to a preferred embodiment of the invention. In an initial step 601, a control device may be paired with an electronic system (for example, such as a personal computer, gaming console, or home theater or media center) as a primary control device, for example either as an automatic process (such as when an electronic system or controller is first powered on) or manually (such as by direct user action to initiate pairing). In an optional next step 602, a plurality of additional control devices may be paired with the primary control device, for example for a user to use a control device in each hand, or for multiple users to each pair one or more control devices for their own use in a group arrangement (for example, for multiple users playing a video game together). In a next step 603, the primary control device may send a plurality of user interaction to a paired electronic system, for example when a user presses a button or makes a selection. In an optional next step 604, any of the plurality of additional control devices may send a plurality of user input to the primary device, and the primary control device may then send the user input to a paired electronic system. In a next step 605, a paired electronic system may send a plurality of feedback to the primary control device, such as instructions for haptic feedback (for example, to activate a vibration motor) or information for presentation on a visual display operated by a control device. In an optional final step 606, the primary control device may transmit a plurality of feedback to an additional control device, for example if feedback was sent from an electronic system intended for a connected additional control device. In this manner, it can be appreciated that all communication between control devices and electronic systems passes through and is facilitated by the primary control device.

FIG. 8 is a block diagram illustrating components of the adaptable fitness system 800, according to one embodiment. The adaptable fitness system 800 includes hardware devices 802, a host device 810, and a fitness server 818.

The hardware devices 802 include a motion sensing device 804, a left hand controller 806A, and a right hand controller 806B. The motion sensing device 804 is mounted on a user's body and detects the user's physical motions, which allows the users to interact with a fitness application 813 operating on the host device 810 by performing motions. An example motion sensing device 804 is described in detail with reference to FIGS. 9A and 9B. The hand controllers 806A, 806B include buttons that the user can press to interact with a fitness application 813. For easy access, one or both of the hand controllers 806A, 806B may be mounted on the handles of a piece of exercise equipment. An example hand controller 806 and mounting system is described with reference to FIGS. 9C and 9D, respectively.

In alternative embodiments, additional hardware devices 802 may be used. For example, the hardware devices 802 may also include athletic shoes with embedded sensors or motion sensors that attach directly to a fitness device. In addition, some of the hardware devices shown 802 shown in FIG. 8 may be omitted. For example, only one of the hand controllers may be used, or the two hand controllers 806A, 806B may be replaced with a combined hand controller that contains the all of the buttons that would normally be distributed between the two hand controllers 806A, 806B.

As a whole, the hardware devices 802 can be used to adapt a fitness device (e.g., a step machine, an elliptical machine, a treadmill, a rowing machine, etc.) into a game controller that receives a user's physical input (both motions and button presses) and generates corresponding input data for interacting with a fitness application 813. For example, the input data could be used to control a virtual character or object in the fitness application.

In some embodiments, multiple sets of hardware devices 802 may be added to the system 800 to adapt additional fitness devices into additional game controllers. For example, multiple stationary bicycles may be adapted into controllers for a bicycle racing application, thus allowing multiple users to participate in virtual races against each other.

Input data from the hardware devices 802 are sent over communication links 808A, 808B, 808C (hereinafter referred to collectively as 808) to the host device API 812 on the host device 810. The communication links 808 may be wired or wireless connections. In one embodiment, the communications links 808 are based on the Bluetooth Low Energy (BLE) protocol, and the hardware devices 802 are BLE devices. If additional sets of hardware devices 802 are included in the system, additional communication links 808 are established to connect the hardware devices 802 to the host device 810.

In the illustrated embodiment, the communication links 808 connect each hardware device 802 directly to the host device 810. In this embodiment, the three hardware devices 802 connect simultaneously to the host device 810 over the communication links 808A, 808B, 808C.

The hardware devices 802 may all connect over the same communication protocol (e.g., Bluetooth Low Energy), or over different communication protocols.

In another embodiment, only the motion sensing device 804 is connected directly to the host device 810 via the first communication link 808A. In this embodiment, the two hand controllers 806A, 806B are coupled to the motion sensing device 804 via the other two communication links 808B, 808C, and the motion sensing device 804 is configured to relay input data from the hand controllers 806A, 806B to the host device 810. This embodiment is described in more detail with reference to FIG. 9A.

The host device 810 includes interface software 811, a host device API 812, and one or more fitness applications 813. As a whole, the host device 810 is a computing device that is capable of executing program instructions. The host device 810 may be, for example, a smartphone, tablet computer, laptop computer, or desktop computer.

The interface software 811 and the host device API 812 operates in conjunction with the interface software to act as an interface between the hardware devices 802, the fitness applications 813, and the fitness server 818. When no hardware devices 802 are connected, the host device API 812 initiates a scan for hardware devices 802 at fixed intervals. Button presses on the hand controllers 806A, 806B or motion on the motion sensing device 804 will trigger the respective device to broadcast for connection (if not already connected). If the device's broadcast overlaps with one of the host device API's scanning intervals, then the host device API 812 initiates a connection attempt to the respective device. This process of establishing a connection after detecting a button press or motion allows for intuitive connection of hardware devices 802 to the host device 810. The host device API 812 maintains the connection between a fitness application 813 and a hardware device 802 as long as the application 813 remains active. After establishing a connection with one or more hardware devices 802, the interface software 811 and host device API 812 receive and process input data from the hardware devices 802 so that the input data can be used to control an application 813. For example, the input data can be used by the application 813 to control a virtual character or object in a game.

The host device API 812 can distinguish the input data from the different hardware devices because the firmware of each hardware device can be configured to include an identifier (e.g., a binary value) in a header of any input data that is sent to the host device 810. Thus, the motion sensing device 806 would have a different identifier than the hand controllers 806A, 806B. The interface software 811 can then build a software state representation of each device based on the device's identifier, and the host device API 812 can map input data to its respective software state representation to identify the originating hardware device. After the input data is mapped, e.g., via a table or index, to the corresponding hardware device, the data can be used to as inputs to fitness applications 813. In embodiments where the motion sensing device 804 is configured to relay input data from the hand controllers 806A, 806B to the host device 810, the motion sensing device 804 may be configured to read the identifier in the input streams from the two hand controllers 806A, 806B and relay a single integrated input stream to the host device 810. This process is described in more detail with reference to FIGS. 9A and 9D.

In some embodiments, the left and right hand controllers 806A, 806B are manufactured to be identical (e.g., to reduce manufacturing costs) and have the same identifier. In these embodiments, it may be difficult to automatically distinguish between the input data from the two hand controllers 806A, 806B, so the interface software 811 may prompt the user to manually identify the two hand controllers (e.g., by first pressing a button on the left hand controller 806A and then pressing a button on the right hand controller 806B.) This setting can then be stored by the interface software 811 as part of the device's software state representation.

The interface software 811 can use a similar process to distinguish input data from different hardware devices when multiple sets of hardware devices are connected to the host device 810 (e.g., for a multiplayer game). For example, the interface software 811 may display a prompt to move a first motion sensing device 804 (e.g., attached to a stationary bicycle), then display a prompt to move a second motion sensing device 804 (e.g., attached to an elliptical trainer), and then display similar prompts to identify the respective hand controllers 806 on the two fitness devices.

In one embodiment, signals from the hand controllers 806A, 806B and motion sensing device 804 are wirelessly sent to the host device 810 as input data using a custom Bluetooth GATT profile. The data sent from the hardware devices 802 are then processed by the host device API 812.

An example of the dataflow between the hardware devices 802 and the host device 810 is presented below:

-   -   1. The motion sensing device 804 acts as a server and the host         device 810 connects as a client.     -   2. The host device 810 (the client) subscribes to data         notifications of a specific service feature of the motion         sensing device 804, such as an accelerometer.     -   3. A reading from the service feature (e.g., an accelerometer         reading) is taken from motion sensing device 804.     -   4. The reading is sent to the host device 810 (the client         subscriber). For example, the three-axis accelerometer reading         may be sent as three bytes.     -   5. The interface software 811 decodes the reading and makes the         readings available to applications 813 via the API 812. The         readings are interpreted as input data by the application 813         and allow users to make selections or to control/manipulate         elements (e.g., objects, characters, etc.) within the         application 813 or to react to game cues or other interactive         elements within the application 813.

The fitness applications 813 are applications that receive input data from the hardware devices 802 through the host device API 812 and carry out some sort of user interaction based on the input data. For example, the fitness applications 813 can be exercise games or any non-game application that can interact with a fitness device in a meaningful way (e.g., an application 813 interact with hardware devices 802 mounted on a treadmill to simulate a walk through a park).

Applications 813 (including games) may be configured to encourage the user to exercise. As the user exercises, data received from the hardware devices 802 is recorded on the host device 810 to reflect progress in the user's experience. Applications 813 can also connect to a fitness server 818 through the network 816, where user data and statistics can be stored and accessed.

One example of how the hardware devices 802 can interact with the software on the host device 810 could be a user attaching the motion sensing device 804 to the pedal of a stationary bicycle. An accelerometer in the motion sensing device 804 measures the motion of the pedals, allowing for realistic control of a ‘virtual biking’ application 813. Another example of how hardware devices 802 interact with software could be a user attaching the motion sensing device 804 to their hip, with the motion sensing device 804 detecting that motion for a dance or exercise game.

The host device API 812 may be configured to run on any suitable operating system, such as iOS, Windows/Mac/Linux or Android. Different versions of the host device API 812 may be created for different operating systems. Although shown as a separate entity within the host device 810, the host device API 812 is typically a separate code library that is compiled into a fitness application 813 at build time. This allows a third-party developer can write a fitness application 813 that uses functions in the host device API 812 to exchange data with the hardware devices 802 and the fitness server 818.

The fitness server 818 includes a cloud services module 820, a fitness database 822, and an application database 824. The fitness server 818 and its components 820, 822, 824 may be embodied as a single device or as a cluster of networked devices (e.g., a cluster of web servers).

The cloud services module 820 receives historical data, such as physical activity and game performance data, from the host device API 812 and stores the data in the appropriate database 822, 824.

The cloud services module 820 also allows users to access their information on any device and at any time. The module also processes user requests to compare and share scores on third-party servers 826, such as social networking systems, e.g., FACEBOOK and TWITTER.

The cloud services module 820 can also host multiplayer games. In one embodiment, games are hosted in asynchronous context. After a user set ups a challenge, the cloud services module 820 can give a user a window in time to finish his “turn” or just wait until he completes a given goal. This information is stored in the application database 824. The cloud services module 820 executes the logic of the games, challenges, or goals that are created between players and maintains their states and progression.

In an alternative embodiment, the cloud services module 820 also hosts multiplayer games in real-time, with real-time game data moving back and forth between players on different host devices 810.

The databases 822, 824 may be stored across a cluster of several servers for scalability and fault-tolerance.

The cloud services module 820 also performs functions associated with the processing of movement units. Movement units are a standard unit of measurement across different types of fitness devices. These movement units are defined by a standard movement signature from the motion sensing device. In one embodiment, the movement units are normalized to provide consistency between differing types and makers of fitness equipment. A normalization table can provide a cross reference between devices for later retrieval and analysis for comparison on a standardized basis. In one embodiment, a standard movement signature is achieved when an accelerometer on the motion sensing device 804 crosses a particular g-force threshold. For example, a standard movement signature may be defined as a deviation of 1 G from a moving average of 20 accelerometer samples collected over 333 ms. In general, movement units may be defined based on any number of parameters, including calorie burn or heart rate. Additional software functionality may be added to the host device API 812 or the fitness applications 813 to improve the accuracy of movement units. For example, if calorie burn is the main parameter, then an option to select the type of fitness machine being used may be added).

A user can create a personal goal to achieve a set number of movement units in a given time period. For example, a goal can be 50,000 movement units in one week. These personal goals can then be shared with friends within a social network.

Users can create also cooperative goals for a group in a social network to achieve a set amount of movement units. For example, a group of five people may set a goal to achieve 250 k movement units for the week.

Movement units can also be used as a basis for activities that benefit from normalization of data for comparison purposes. For example, movement units can be used in competitions between groups or friends in a network. Challenges can be issued and broadcast to a user's friends on social network.

In one embodiment, the cloud services module 820 retrieves a user's social graph from a social networking system on a third-party server 826 and reproduces the social graph on the fitness server 818. Thus, subsequent functions associated with social game mechanics (e.g., the creation of challenges and cooperative goals) can be executed on the fitness server 818. FIG. 9A is a block diagram illustrating the components of the motion sensing device 804, according to one embodiment. The motion sensing device 804 includes sensors 902, a communication module 908, and firmware 910.

The sensors 902 detect the user's physical motions. In the illustrated embodiment, the sensors 902 include an accelerometer 904 and a gyroscope 906. However additional or different sensors 902 may be included in the motion sensing device 804.

The communication module 908 interacts with the communication link 808A to transfer data between the motion sensing device 804 and the host device 810. For example, the communication module 908 may receive input data from the sensors 902 and send the input data to the host device 810 to be used by a fitness application 813. In one embodiment, the communication module 908 connects via the Bluetooth Low Energy (BLE) protocol. The firmware 910 contains logic that manages the operation of the motion sensing device 804. For example, the firmware 910 may contain logic to support a “shake to connect” function that monitors the sensors 902 and establishes the communication link 808A to the host device 810 upon detecting that a user has shaken the motion sensing device 804.

In an alternative embodiment described with reference to FIG. 8, the two hand controllers 806A, 806B are coupled to the motion sensing device 804 and the motion sensing device 804 is configured to relay input data from the hand controllers 806A, 806B to the host device 810. In this alternative embodiment, the firmware 910 is configured to detect and connect to the hand controllers 806A, 806B independently of the host device 810, and the communication module 908 maintains the connections with the hand controllers 806A, 806B after they are established. The connections with the hand controllers 806A, 806B may be under the same communication protocol as the communication link 808A (e.g., Bluetooth Low Energy) or a different communication protocol (e.g., an RF connection). Meanwhile, the firmware 910 manages the three connections (the connections with the two hand controllers 806A, 806B and the communication link 808A with the host device 810) and relays input data from the hand controllers 806A, 806B to the host device 810. In some embodiments, the firmware 910 may be configured to combine the input data from the sensors 902 and the hand controllers 806A, 806B into a single integrated input stream. Thus, the host device API 812 receives a single input stream that includes inputs from all three hardware devices.

FIG. 9B illustrates a motion sensing device 804, comprising an outer enclosure or shell 912 and internal electronic components 913, according to one embodiment. As described above with reference to FIG. 8, the motion sensing device 804 attaches to the user (e.g., around the leg) and uses sensor 902 to measure the user's movements, which are recorded as input data and sent to the host device 810. As shown in FIG. 9B, the motion sensing device 804 is housed in a small enclosure 912 so that it can be attached to the user in multiple ways. In the illustrated embodiment, the motion sensing device 804 connects wirelessly to the host device 810 and is powered by a battery.

FIG. 9C illustrates a hand controller 806, according to one embodiment. The hand controller 806 includes a handle 914 and a strap 916. One or more buttons 918 are mounted on the handle 914. The handle 914 may also include a directional pad or joystick either in addition to or in place of the buttons 918. As described above with reference to FIG. 8, the hand controller 806 communicates with the host device 810. In the illustrated embodiment, the hand controller 806 communicates wirelessly and is battery powered.

Internally, the hand controller 806 includes a radio and a microcontroller. In one embodiment, the radio is an RF radio that connects to the motion sensing device 804 and sends an input signal to the motion sensing device 804 to be relayed to the host device 810. In an alternative embodiment, the hand controller includes a Bluetooth Low Energy (BLE) radio and a system on a chip (SoC). In some embodiments, the radio, microcontroller, and any other electronic components of the hand controller 806 may be placed on a single printed circuit board.

FIG. 9D illustrates an example of hand controllers 806A, 806B mounted to handlebars of a fitness device, according to one embodiment. The straps 916 of the hand controllers 806A, 806B are wrapped around the handlebars. In one embodiment, the bottom side of the handle 914 may include an adhesive substance to increase the friction between the hand controllers 806A, 806B and the handlebars.

To reduce manufacturing costs, some or all of the components of the two hand controllers 806A, 806B may be identical. In one embodiment, the two hand controllers 806A, 806B are completely identical (e.g., same mechanical enclosure, internal electronics, and firmware). In this embodiment, it may be difficult for the firmware 910 or the host device API 812 to distinguish between the two hand controllers, and the interface software 811 may prompt the user to identify each hand controller as described above with reference to FIG. 8. In another embodiment, the two hand controllers have the same internal electronics (e.g., the same microcontroller, radio, etc), but may be placed in different enclosures to identify one controller as the left hand controller 806A and the other as the right hand controller 806B. For example, the buttons 918 on the two hand controllers may have a different layout or different colors, or the housings may have symmetric ergonomic features so that they are better suited for a user's hands. The two hand controllers 806 may also be flashed with different firmware so that the motion sensing device 804 or host device API 812 can distinguish between the input data from the two controllers 806. For example, the firmware on the left hand controller 806A may be configured to send an identifier (e.g., a binary 0) in a header of its input stream, while the firmware on the second hand controller 806B may be configured to send a different identifier (e.g., a binary I) in a header of its input stream.

FIG. 10 is a flow chart illustrating an exemplary process for interacting with a fitness application 813 based on a user's interaction with a fitness system, according to an embodiment of the invention. A user begins by attaching hardware devices 802 to a fitness device or the user's body; hand controllers 806A, 806B or motion sensing device 804 may either be held in the user's hands or attached to a fitness device, depending on a particular fitness application 813.

According to the embodiment, motion sensing device 804 obtains 1005 real-time motion data comprising acceleration data from accelerometer 904 or rotation data from gyroscope 906, as the user interacts with a fitness system. A fitness system is not limited to a stationary exercise machine such as a treadmill, but may also include dynamic means of exercise, such as running on a road. Data obtained by motion sensing device 804 may be transmitted to a host device 810 over established communication links 808.

Based on data obtained 1005, interface software 811 on a host device 810 may determine 1010 an activity-specific motion signature. The activity-specific motion signature may identify the current activity performed by a user. According to the embodiment, the motion signature may act as a basis against which future movements may be compared by a fitness application 813.

According to the embodiment, the interface software 811 may generate one or more activity vectors 1015 based on a motion signature. Activity vectors represent metrics associate with the activity level of the user. For example, the activity vectors may represent the number of calories burned by a user, the distance covered over a specific time interval, or the intensity level of the user. The activity vectors are a standard unit of measurement across different types of fitness devices.

According to the embodiment, the user interacts 1020 with a fitness application 813 based on the activity vector generated 1015 by interface software 811. By altering the intensity with which a user performs a fitness activity, the user changes the activity vector over a period of time. The change in the activity vector alters the state or behavior of an object in the fitness application 813, thereby allowing the user to interact with fitness application 813 on a host device 810. For example, if the user is playing a running video game, where the user's character is running on the screen through an obstacle course, the intensity at which the user runs on the treadmill or cycles on a bicycle influences the speed at which the user's character (the object in application 813) run across the screen (behavior exhibited by the object) in the game. Thus by running faster, the user changes the activity vector in real-time, corresponding to an increase in speed of the user's character. The user may also interact with the application based on input from the hand controllers 806. For example, the user could press a button on the hand controller 806 as the user's character approaches an obstacle in the video game, causing the user's character to jump over or avoid the obstacle.

In some embodiments, variant database architectures such as column-oriented databases, in-memory databases, clustered databases, distributed databases, or even flat file data repositories may be used according to the invention. It will be appreciated by one having ordinary skill in the art that any combination of known or future database technologies may be used as appropriate, unless a specific database technology or a specific arrangement of components is specified for a particular embodiment herein. Moreover, it should be appreciated that the term “database” as used herein may refer to a physical database machine, a cluster of machines acting as a single database system, or a logical database within an overall database management system. Unless a specific meaning is specified for a given use of the term “database”, it should be construed to mean any of these senses of the word, all of which are understood as a plain meaning of the term “database” by those having ordinary skill in the art.

Similarly, most embodiments of the invention may make use of one or more security systems 36 and configuration systems 35. Security and configuration management are common information technology (IT) and web functions, and some amount of each are generally associated with any IT or web systems. It should be understood by one having ordinary skill in the art that any configuration or security subsystems known in the art now or in the future may be used in conjunction with embodiments of the invention without limitation, unless a specific security 36 or configuration system 35 or approach is specifically required by the description of any specific embodiment.
